Life Extension Mega Vitamin K2, 45000 mcg (45 mg), 30 capsules

Vitamin K is essential for bone mineralization. This bone-friendly nutrient is a cofactor for the carboxylation of osteocalcin, a protein produced by osteoblasts that is responsible for binding calcium and depositing it in the bone. This processed is called bone mineralization.^1,2

Why is this important? Because if you’re not getting enough K2, osteocalcin doesn’t undergo carboxylation and remains in its inactive form, which means it cannot bind to calcium and play its role in bone formation.²

Bone density and menopause

Women go through a rapid phase of bone loss during menopause, in addition to normal, age-related bone loss—which happens at roughly the same rate as men. But studies of postmenopausal women showed that taking vitamin K2 helped maintain and even increase bone mineral density.^3-6

If you’re concerned about maintaining bone strength and healthy bone density, consider adding Mega Vitamin K2 High Potency for Strong Bones to yLife Extension's daily regimen. It delivers 45,000 mcg (45 mg) of vitamin K2 (menaquinone-4) in every dose, the same amount shown to support bone mineral density.
